Application led July 17,

To @ZZ 'Lo/tom t may concern:

Be it known that I, CHARLES C. HoGnN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful improvements in Couplings, of which thefollowing is a specilication.

The invention relates to couplers, and has for its primary objects; theprovision of a coupler adapted for useV in coupling to cars havingcouplers at various heights; the provision of an improved arrangement ofbuffing rollers; the provision of a construction in which the parts maybe easily assembled; and in general the simplification and improvementof coupler mechanism. Certain embodiments of the invention areillustrated in the accompanying drawing wherein- Figure l is a plan viewof one form of the apparatus, Fig. 2 is a section on the line ill-Il ofFig. 1, Fig. 3 is a tace view oi' the apparatus oi' Fig. 1 with thecarriage and parts carried thereby removed, Fig. et is a transversesection through a modified form oi apparatus, and Fig. is a plan view ofthe carriage shown in section in Fig. L1.

Referring to Figs. 1, 2 and 3, 1 is the end of the car upon whichismounted the transversely extending head 2. This head, as indicated inFigs. `2 and 3, is hollow and provided with the outwardly curved slot 3extending substantially throughout its length, correspondinglycurvedoverhanging lips L1 and 5 being provided above and below the slot.

Mounted in the head for transverse movement along the arc of the curvedslot is the carriage 6. This carriage consists of a hollow castingprovided at its front end with the three coupler pockets 7, 8 and 9having alined perforations to receive a coupling pin. T his arrangementpermits of the use of the apparatus with cars having their couplers atvarying heights.

Mounted in the carriage in front of the lips 4C and 5 are the butlingwheels 10 and 11 on each side of the vertical center line of thecarriage, such wheels being arranged in pairs with one pair lying abovethe slot in the head and the other pair lying below such slot. Similarlymounted to the rear of the lips 4 Specification of Letterselatent.`

and 5' are the pairs of wheels 12 and 18. Jihese wheels are secured inthe carriage by means of the headed pins 14, a groove or runway beingprovided in theupper surface of the head pocket to receive such heads.The pins are inserted through the perforations 15 shown in Fig. 1.

The apparatus as above described is simple, can be cheaply constructed,and easily assembled. The coupler can be used to couple at varyingheights, and the bu'l'ling and pull ing strains imposed upon the deviceare well taken care of by the sets of rollers or wheels arranged insideand outside the overhanging lips 4 and 5. The pockets 7, S and 9 can beused with the usual coupling link 16 as illustrated in Fig. 1.

Figs. et and 5 illustrate a modification in which the head 2 issubstantially the same as in the other type of apparatus, butchecarriage 17 is of a different type, the iront end thereof terminatingliush with the faces of the bearing lips 18 and 19. The carriage ishollow and is provided with a headless coupling pin 20. is indicated inFig. 4 the space between the upper and lower walls of the carriageissuch that the coupling link 21 can be tilted up or down a considerabledistance thus permitting coupling with other coupling devices lyingabove or below that illustrated. The carriage is provided with two setsor rollers or wheels 22 and 23 engaging the rear sides o1 the lips 18and 19, the rollers being held in position by means of headed pins 24;corresponding to those einployed in the other type of apparat-us.

Vf hat I claim is:

ln combination, a hollow transversely extending iead slotted along itsfront side and provided with opposing overhanging lips spaced apart, acarriage lying inside the head and provided upon its upper and lowersides With wheels engaging the said lips, a headed bearing pin passingthrough the carriage and the upper and lower wheels, and acoupler pocketon the carriage `projecting torwardly, the upper wall ci the interior oithe head being grooved to receive the vhead of said bearing pin.
